To all whom it ma concern:

Be it known t at I, FR D SoHMrrrn, a

citizen of the United States, residing at- Glayton, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Shingles, of which the following is a specification.

My invention relates to an improvement in shingles, and appertains more particularly to a shingle capable of interlocking with similar shingles. An object of my invention is to produce a shingle made of a plastic composition, preferabl reinforced concrete, which will consequently be easy and cheap to manufacture, and, ifnecessary, a shingle that can be manufactured upon the premises.

A further object of my invention is to utilize a cheap, plastic composition, such as concrete, and to effect a saving in the form and material of shingle now on the market. Owing to the scarcity of good wood, it is practically impossible to produce a wooden shingle which is capable of doing the work, unless at a prohibitive price.

In the accompanying drawings, forming section taken on the line with a downwardly-projecting wall 3. The

body portion 1 is provided with a shoulder 4, and terminates in an extension 5, which is formed into a downwardly-projecting lug 6 of a rather restricted width.

Specification of Letters Patent.

Application filed July 24, 1917. Serial No. 182,429.

On one side of the shingle is an L-shaped extension 7 forming a longitudinal channel 8, and on the other side is a similar extension 9, extending in the opposite direct on, and forming a longitudinal channel 10, similar to the channel 8. The tongue 5 is provided with tapering reduced portions 11, 11, on either side of a longitudinal rib 12, to which is attached the downwardly-projecting lug 6.

In the body of the shingle I provide two 'nailing'openings 13 and 14, respectively.

In operation, a shingle is put in place, such as disclosed in Fig. 1, at the bottom, and another shingle is laid with the wall 3 engaging the shoulder 1 and resting upon the tongue 5, as disclosed in Fig. 2, and a nail passing through the} openings 13 and 14 holds the shingle to the surface to be covered. Another shingle is laid opposite the others, as disclosed in Fig. 3, wherein the extension 9 cooperates with the channel 8, and the extension 7 fits in the channel 10 to form a secure lock for the shingle.

It will thus be seen that when the shingles are in position on a roof, and fastened thereto by nails driven through the openings, that a securely interlocked surface is produced.

I claim:

A concrete shingle, the exposed portion of which is plain and smooth and rectangular in form, the shingle being provided with vertical edges which are in the form of a tongue and groove extending in opposite dizrections on the two edges, tapering reduced portions and an intermediate longitudinal rib on the upper edge, an inwardly extending lug at the extreme upper end, and the shingle having a recess on the under side.

In testimony whereof I afiix my si nature.

FRED soHMfrTE.
